Among the alloplastic materials available calcium sulphate
has a long history of safe use.
Solubility of calcium sulphate
has been extensively studied during decades since the pioneer contributions by van't Hoff and co-workers at the early twenty century (van't Hoff et al.

The new production line for calcium sulphate
pigment would raise the plant's total capacity from 110,000 tonnes a year to 150,000 tonnes a year.
Line of fillers and functional pigments includes clays (water-ground kaolins and bentonites), mica (muscovite and biotite), barytes (natural white and off-white grades), calcium sulphate
, calcium carbonate, and the Polytal series of platy talcs designed specifically for polyolefins.
This is not the case where sulphuric acid was formerly neutralised with lime as IMP Ecomag does not form insoluble calcium sulphate
, says Industrial Metal Processes.
The Finnish chemical industry group Kemira Oyj said today (19 December) that its subsidiary Kemira Chemicals Oy would increase its calcium sulphate
pigment production by investing EUR5m into expansion of its pigment plant in Siilinjarvi, Finland.
This is a chemical process whereby the sulphur oxides produced in carbon combustion processes are captured and washed as they come out of the boilers, they are then coated with limestone which reacts with the sulphur dioxide (SO2) producing a mixture of sulphite and calcium sulphate
